The Lowdown
Alright, Rusty here. Let’s have a look at what’s cookin’ for the coming days.
Right off the bat, we’ve got a pretty slow start. Saturday the 8th is a write-off – tiny, weak swell with barely any energy to speak of. You’re looking at 1ft of south swell that’s just not gonna do anything for you. The wind is glassy in the morning, but the waves are so small it’s not worth paddling out. That afternoon picks up a touch to 3ft, but the wind swings cross-off and the combined energy is still only moderate (211). Not enough to get excited about.
But hold tight, because Sunday the 9th kicks things up a notch. The morning sees a solid 7ft SSW groundswell, with a long period of 14 seconds, and the combined energy jumps to a strong 1548. The wind is light and cross-off, so the waves will be clean. This is for experienced surfers only – 7ft is a solid step up, and the long period means it’ll be packing punch. The best bet here is Jaconé itself, which is exposed to the south swell. The crowds are sometimes a factor, so keep an eye out. This is the standout of the whole run.
Monday the 10th stays big, but the wind gets messy. Still 7ft to 8ft of south swell, but cross-on winds and some rain make it choppy and marginal. Not worth the hassle unless you’re desperate.
Tuesday the 11th is a return to form. Morning and afternoon both have 8ft to 8ft south swell, 13-second period, and the combined energy is very strong (1972 and 2210). The wind holds cross-off all day, so the waves are clean. Again, this is expert territory – 8ft is big, powerful, and the long period will make it grind. If you’re skilled, this is a proper session.
Wednesday the 12th is still pumping. 7ft south swell, 12-second period, and the morning has offshore NE wind at 20 km/h – that’s clean and groomed. The combined energy is strong (1240). This is another excellent window for experienced surfers.
From Thursday the 13th through Saturday the 15th, the swell drops a little but stays in the 5ft to 6ft range, still south and still with decent period. The standout is Saturday morning the 15th – glassy conditions, 6ft south swell, 13-second period, and the combined energy is strong (1236). Zero wind, just clean lines. That’s a magic morning if you can get out.
After the 15th, the swell fades. Sunday the 16th has 5ft to 6ft, but by Monday the 17th the period drops to 7 seconds and the energy falls off a cliff. The wind picks up strong, too. By Tuesday the 18th, we’re looking at 5ft of short-period windswell from the east, with fresh breeze. Not great.
There’s a bit of a rebound on Wednesday the 19th morning – 7ft of ENE windswell, 8-second period, but the wind is offshore NE and gentle, so it’ll be clean. The combined energy is moderate (857). Not the quality of the south groundswell, but a fun option for a morning paddle.
After that, it trails off into tiny, weak waves for the rest of the run. Thursday the 20th through Sunday the 23rd is all 2ft to 4ft, poor energy, and mostly onshore wind. Not worth your time.
So the big call here: Sunday the 9th and Tuesday the 11th mornings are the best of the lot. Big, powerful south groundswell, clean winds, and plenty of energy. This is expert surf – don’t take it lightly. The glassy Saturday the 15th morning is also a beauty, a little smaller but still solid.
Stay safe out there.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
